REAR-AXLE TRUSS.

messie.

To all/whom may conce/m Be it known that I, HERMAN H. SUNVOLD, a citizenof the United States. residing at Sacred Heart, in the county ofRenville and State of' Minnesota, have invented certain new and usefulImprovements in Rear-Axle Trusses, of which the following is aspecilication, reference being. had therein to the accompanyingdrawing.. l

This invention relates to a rear axle truss for automobiles, and theprincipal object of the same is the provision of a simple and efficientsupporting means .for bracing the axle at its central portion. i f

Another object otthis invention is the.

production 'of a truss which is provided with a plurality of clampingmembers which are so formed as to securely hold the truss rods in theircorrect position upon the rear axle.

With these and other-objectsthis inven-. tion consists of certain novelcombinations, constructions and arrangements of parts as will behereinafter fully described and claimed.

ln the accompanying drawing: Figure l v is an elevation Aot the rearaxle and other oor-tions of an automobile showing the truss membersattached thereto. Fig. 2 is a section taken on the line 2-2 of Fig.` l;Fig. 3 is a section taken on the line 3-3 of F ig. l. vFig. 4 is adetailed perspective view of one of the clamps. Fig'. 5 is a plan viewof the complete truss showing the same detaehed.

Referring to the accompanying drawing by numerals l indicates the usualaxle which I is supported by the wheels 2 and which is provided at itscentral portion with the gear housing 3. p

In order to prevent the axle l from break-` ing atthe central portion oradjacent the housing 3 and for the purpose otsupporting the axle in itscorrect position so as to allow the gear withinthe housing 3 toefficiently operate there are provided a plurality of truss rods whichextend upon the outer portion or" the axle and which bear thereon toeiliciently support the same. A truss rod 4 extends so as to brace therear portion ot the axle l by bearing upon the rear portion ofv thehousing 3 while the truss rod 5 extends under the axle as clearlydisclosed in Fig. l so as to support the same. It will be seen that thetruss rods e and 5 areeach provided at their central portion wlth aSpecification of Letters Patent.

rods in their correct position upon the axle y l. Each clamp comprises aprimary section 7 and an auxiliary section 8 which `are bowed so as tolit upon the axle l. l The auxlliary section 8 is provided withlaterally extending feet 9 which are adapted-toengage the laterallyextending feet 1G of the primary section 7. "Securing boltsll arethenpassed through these feet 9 and .l0 for securely holding the clampsin their correct position upon the axle. The primary sec- .tion'flisprovided with the depending lug l2' upon its' lower side which isprovided vwith "a transverse opening 13 for vthemecep-` tionj of thelower truss rod 5. rllhis truss rod 5 is provided with a head le forpreventing the rod from moving` from engagement with the lug l2. Betweenthis lug l2 and one of the feet l0 there is provided a diagonallyextending lug l5 haviiiga transverse opening '16 adapted to' receive thetruss rod 4, this-truss rod being provided `with the 'usualhead lll.Since theselugs l2 and 15 are formed upon the'primary scction 7 as abovedescribed they-.will be formed ata spaced distance apart so .as toeasily engage the truss rods 4 andVor holding the truss rods in theircorrect spaced relation upon the rear axle whereby the rear axle will beehoiently supported.

From the above description :will be seen l that the" sections may beeasil n taken apart when it is desired to remove tie truss mehr ber fromthe rear axle or when it is desired to place thev same thereon wherebyany changes which are desired to be made may be easily done withoutinterference from the truss member.

What is claimed, is

ln a rear axle truss for automobiles, the Combination with an axle, aplurality of truss rods. one oi" said rods adapted to fit upon the lowerportion oft the axle and the other rod' ada y ted to fit upon the rearportion ot the ax e7 a clamp carried by the axle adjacent euch endthereof, each clamp comprising a primary and an auxiliary sect-ion,

Said sections adapted to loe secured together for holding said clamp inposition, each of said primary sections provided upon its lower sideWithl a depending lug, each of said primary sections also provided witha diagonally extending lug formed adjacent said depending lug, said lugsprovided with transverse openings adapted to receive said t-russrodswhereby said truss rods will eiiciently brace the central portion ofthe. axle,

said lugs being formed in a position to effi- 10 oiently hold said trussrods 1n their correct positions.

In testimony whereof I hereunto aix my signature in presence of tWoWitnesses.
